Hi,

local: Windows7, and shell comman is cmdproxy.exe/cmd
GNU Emacs 27.0.50 (build 1, x86_64-w64-mingw32) of 2017-11-24

In general dired buffer, if I call dired-do-shell-command on marked file
with end "&", it will call "start /b ..." to run asyn shell command.
However, it hould not happend for tramp dired buffer if the
tramp-remote-shell is not cmd.

For example, my server is linux and tramp-remote-shell is "/bin/sh". If I
run dired-do-shell-command with end "&", it suppose to send the command
directly, but it add "start /b" actually.

I attached the tramp debug for your reference.


Tramp setting:
  (push '("plink"
           (tramp-login-program        "plink")
           (tramp-login-args           (("-l" "%u") ("-P" "%p") ("-ssh")
("%h")))
           (tramp-remote-shell         "/bin/sh")
           (tramp-remote-shell-args    ("-c"))
           (tramp-copy-program         "pscp")
           (tramp-copy-args            (("-l" "%u") ("-P" "%p") ("-scp")
("-p" "%k") ("-q") ("-r")))
           (tramp-copy-keep-date t)
           (tramp-copy-recursive t)
           (tramp-default-port         22))
        tramp-methods)



Best Regards,

Thanks for testing. So I mark this bug as closed.

Hmm. I still don't understand why you want to change
default-directory. Or do you want to say it doesn't matter, when
explicit-shell-file-name is set?

And even in case there is no explicit-shell-file-name set,
read-file-name shall work as expected with the existing default-directory.

Best regards, Michael.
